This is my first post but I have been reading your site for years now. Your advice on safe use of Lithium cells was particularly useful.
Last year I bought about 20 AGFA branded CR123A cells.(Boxed from a reputable dealer). Although they are dated November 2021, I have found that only about half are fully charged with the rest anywhere down to 20%. I use a ZTS Pulse Load Multi Battery Tester to test all my cells before use and only use matched cells in my flashlights. Several of these are 2 Cell flashlights that I keep in the cars for emergencies. My concern is that the charge state can measure anywhere from 40% today to 100% tomorrow, so obviously I'm concerned that my 2 cell flashlights may not be that safe after all.
For my EDCs I use 18650s or single cell (CR123 / AA) for pocket carry. The flashlights I keep in the cars are older EDC's from before I changed to 18650s a couple of years ago. Whilst I don't really want to get rid of the 2 cell flashlights, I can't afford for my wife to use any flashlight that is potentially unsafe.
I don't think my tester is faulty as it has no issues with other batteries and I replace the batteries in it regularly. Other brands of CR123A don't seem to have the same issues. Do your members have any views or opinions on what might be the problem here?
